Yield:1215-59-4 99% ，1953-54-4 1%

Reaction Conditions:

with hydrogen;5% rhodium-on-charcoal;iron(II) acetate in tetrahydrofuran at 20; for 9 h;

Steps:

39

Following a procedure similar to Example 32, 4-benzyloxy-2-(2-pyrrolidinylvinyl)nitrobenzene as a starting material was reduced in the presence of 5 % rhodium/carbon powder and as a metal compound, ferrous(II) acetate, nickel(II) nitrate or cobalt(III) acetylacetonate as the catalyst of the present invention. The results are shown in the following Table 5, and in the case where the reducing agent of the present invention was used, 5-benzyloxyindole was obtained in a higher yield and 5-hydroxyindole was byproduced in a lower yield, compared to Comparison Example 4.
